Wireless thermometer

I am using a Lacrosse Technologies 9007 wireless thermometer. I got it from Amazon for about $20. Is anyone else using this? It seems to lose it's signal all different times of day and in all different types of environmental conditions. It's range says 260' and I have it just over 100' away, separated by only a thermal pane window and a chain link fence. Am I expecting too much? All I want to do is monitor the coop temperature at critical times. Should I have spent more money on a "better" wireless thermometer? If so, what?

I have a cheap one that I bought at Walmart, and have seen at Home depot & Lowes, for about $10. It claims about 100' and I have no problems with it. However, I have learned that chicken poop goes everywhere. So I put the part that stays in the coop into a plastic baggie to protect it. Also, it is not in direct sunlight or where it is likely to be dropped often. You might want to check the batteries. When my batteries are low it starts to give really weird readings.

Thanks briteday. The batteries were new a week ago but I'll give the batteries a try anyway. If that doesn't help, I'll hit the big box stores and see what they've got. I have the transmitter in a plastic baggie too. It's a messy place. I have it out direct sunlight, so that's not the problem. I do however have all kinds of things that create all kinds of RF, i.e. wireless routers, wireless radio fence and our whole house is lit by cf bulbs. Interference from them perhaps.

Mine is 100 ft range too...think I paid $15 for it at Home Depot or Lowes. I've only been using it since February, but it's worked like a champ so far. It's Accu-Rite brand. I think most of the "cheaper" ones have the 100 ft range limit. If yours advertised more than that - I'd say they're full of it

Ya know.... I read the reviews on a few thermometers from Amazon. In fact, the Accu-rite thermometers got a few bad reviews. I try to keep in mind who is writing these reviews and why. In this case, none of them were using it for a chicken coop. I'll shop around with byc advice instead.

I have an accu rite that I purchased at Lowes and it has worked great for me. Since I keep it in a plastic baggie I don't find the humidity measurement very reliable but the temperature is pretty spot on.
